In IS, flash() is literally just the screen flashing white, with the argument being the duration. You need to pair it with playef() and shake(), but I don't remember the exact values. It's in the second post, though.

112 and 80 are the x and y positions respectively, if you're having trouble with them, use Ved, and the coordinates (I think) are where the top-left corner of the crewmate should go.

blue is just the color of the crewmate (red, yellow, green, cyan, blue or purple)

0 is the mood of the crewmate (0 is happy, 1 is sad, I think)

faceplayer is the AI of the crewmate, An AI can be one of these: followplayer, followpurple, followyellow, followred, followgreen, followblue, faceplayer, followposition (if you choose this one there has to be a sixth variable saying what x position), panic, faceleft, or faceright
